GAS -STOVE.

SPIEGIJEICAIION forming part of Letters Patent No. 288,893, dated November 20, 1883.

' Application filed March 21, 1883. (No model.)

To all whom it may concern:

Be it known that I, Isaac VA'N HAGEN, of Chicago, in the countyo'f Cook and State of Illinois, have invented certain new and useful Improvements in the Manufacture of Stove Boards or Platforms, of which the following is a specification.

My invention has special reference to that class of stoveboards which are made of crys tallized tin; and it consists in an apparatus for effecting the process technically known as burning the sheet preparatory to the treat- I ment thereof with water and mixed or diluted acids, as hereinafter specified. I 5 In an application filed of even date herewith I have described and claimed'a method of producing the semi-melted condition of the surface of the sheet to be treated, and an apparatus adapted for carrying the said method into effect.

The apparatus described in my said application consists in a burning-frame composed of pipes, certain of which areperforated,whereby to produce a large heating-area, said frame being-combined with a regulator, in which gas and air under pressure are mixed, and from which the mixed gas and air are distributed throughout the frame, producing a large number of independent flames of equal intensity to impinge and at the same instant of time to act upon the sheet to produce the desired semimelted condition of its surface.

In the apparatus described in said application the intention is to make the entire frame in one connected structure, and in its use it is found that the length necessarily given to the various sections of pipes entering into its constrnction renders it difficult to prevent the warping or twisting of the frame by reason of the heating and cooling thereof, or the unequal expansion and contraction consequent there upon.

My present invention has for its object the production of a burning or melting frame of the same general character, but made with its upper part in disconnected or independent sections, whereby the pipes composing said upper part may by the limitation of their length be less liable to become warped, twisted, or distorted in shape by the continued changes of temperature to which they are subjected.

In the accompanying drawing is shown an isometrical view of my improved sectional burning-frame.

A are pipes elevated upon legs a,

A is a similar pipe, running centrally between and parallel to the pipes A. The pipes A and A are imperforate, and are divided mid= way of their length at b, the ends of the pipes at b, as also at their outer ends, being closed.

B is a pipe placed in a plane lower than that of the pipes A A, and transversely of said pipes, the pipe B being united with the top of a regulator or gas and air mixer, C, of substantially the same construction described in my said other application filed herewith, and to which I refer for a fuller description.

The gas-pipe leading to the regulator is shown by a/ and the air or blast pipe by b. The pipe B connects with pipes 3', arranged under and parallel with the pipes A and A, and the gas and air mixed are delivered to said pipes A A by a series of vertical connec-- tions, (1. The perforated burning-pipes D run across from the pipes A to those A, and are made only of such length as has been shown by experience will allow them to be repeatedly heated and cooled without becoming warped or twisted out of shape. I have found that twelve inches is a safe limit for the length of the burning-pipes, but do not confine myself to this length. The jet-openings in the burning-pipes D are arranged substantially in the manner described in my said other application.

The special advantage of the sectional burning-fran1e here described, in addition to that above referred to, is that a frame of any desired area can be made by increasing the number of sections. Stop-cocks e may be arranged in the supply-pipes leading to the several sec tions, so that one or more of the same may be shut off or renderedinoperative, or the entire series used together.

I -do not claim, broadly, a gas pipe burningfra-me, nor a regulator for mixing gas and air, unless said regulator is combined substantially in the manner herein set forth; but,

Having described my invention, I claim- 1. In an apparatus for burning crystallized tin plates, the combination of a gas and air supply, a system of imperforate pipes communicating with said supply, and a burningframe in sections placed above said pipes and communicating therewith, substantially as set forth.

' 2. The combination of an upper sectional burningframe, a lower non-sectional system of supply-pipes, and vertical pipe-connections between the same, substantially as set forth.

3. The combination of an upper sectional burning-frame, a lower non-sectional system of supply-pipes, vertical pipe-connections between the same, and legs supporting the whole apparatus in an elevated plane, substantially as set forth.

4. The combination of an upper sectional burning-frame, a lower non-sectional or united system of supply-pipes, vertical pipe-conncc- 2o tions between the same, and means for receiving and mixing gas and air and distributing said fluids throughout the entire tubular system, substantially as set forth.

5. In an apparatus for the manufacture of 25 crystallized tin plates, a gas and air supply, a system of imperforate pipes communicating therewith, an upper sectional burning-frame connected with said system, and suitable cooks for shutting off communication betweensaid 30 sectional frames and from the supply of gas and air, substantially as set forth.

In testimony hereof I hereunto set my hand this 17th day of March, 1883.
